Properties

MaxHeartbeatInterval

Maximum interval between periodic HA heartbeats. The actual runtime heartbeat interval might be shorter if the system decides that more frequent heartbeats are needed for stable operation. (Default: 100ms)

PeerDead

Number of milliseconds of no heartbeats received from the HA peer node before the peer is considered dead. Will be rounded down to a multiple of the actual runtime heartbeat interval. As this is evaluated at every heartbeat interval, the peer node may have been silent for up to one extra heartbeat interval before detection. After the current node starts to take over, there is also additional headroom required up to the full desired max failover-time, to allow switches and/or other neighboring network equipment to learn what happened. It is only after they have been informed about the change, and taken action on it, that the system will be fully operational again with the current node being active. (Default: 1900)

IfaceDown

Number of milliseconds of incomplete heartbeat communication and failed queries to MonitorTargets before a critical interface will be considered down. Bi-directional communication is required. Will be rounded down to a multiple of the actual runtime heartbeat interval. (Default: Auto)

IfaceEarlyDown

Number of milliseconds of incomplete heartbeat communication over a critical interface before the system will start monitoring the MonitorTargets specified on the interface. Anything but functional bi-directional heartbeat communication is considered as incomplete. Must be set to a lower value than IfaceDown. Will be rounded down to a multiple of the actual runtime heartbeat interval. (Default: Auto)

OnDepCacheFull

Decides the action performed when a new object arrives when the dependency cache is full. (Default: Replace)
